Don't know where to put this so I'll put this here:
Today there was a Nintendo Direct for Super Smash Bros for Nintendo 3DS & WiiU. As you may imagine, there was quite a bit of news concerning characters, and of course what franchise has the biggest "cast" of characters than Pokemon? Here's the news for what concerns Pokemon:


(1.) Poke Balls make their return, but there's a slight twist! Poke Balls are items which send out a random Pokemon which can do a variety of things from attacking, creating barriers, becoming obstacles, dropping other items/collectibles, or possibly nothing. However now they're throwing Master Balls into the mix and Master Balls specifically contain Rare and Legendary Pokemon. Now in previous games the Poke Ball could send out a Legendary Pokemon, but in this game they now send out any non-Legendary Pokemon. The following "Ball" Pokemon have been confirmed so far:
Poke Ball: Meowth, Electrode, Goldeen, Staryu, Eevee, Bellossom, Metagross, Chespin, Fennekin, Spewpa, Gogoat, & Dedenne
Master Ball: Mew, Entei, Deoxys, Palkia, Darkrai, Arceus, Victini, Kyurem, Keldeo, Meloetta, & Xerneas

I could post all the screenshots and say what each does, or just link you to Serebii's SSBf3DS&WU Pokeball page while Electrode frowns at you (he's close enough to a Poke Ball, right?).
(2.) The Adventure Mode from previous SSB has possibly been replaced with a new mode called "Smash Run". It's a 4-player co-op which starts with players exploring though an expensive dungeon stage collecting power-ups (all power-ups just adding to the characters basic stats) by defeating enemies and completing challenges for 5 minutes. When the 5 minutes are up, all 4 players fight each other with the power-ups they've collected. While some of the enemies are from the Subspace Emissary, many also come from other game series. One of the enemies that can appear is a Chandelure.

Sorry, screenshots are limited at this time. I can tell you what Chandelure does though: its seen throwing purple fireballs as on move (Will-O-Wisp?) and spinning around creating a flame tornado which is sends toward the player (Fire Spin?).
(3.) It's been confirmed that most stages will only appear in either the 3DS or WiiU game, very few appearing in both. The previously confirmed Lumiose City Prism Tower stage is 3DS exclusive. Also, 3DS stages will only have 2 songs each (WiiU stages will work as they did in Brawl with having a playlist), though at this time we don't know what music will play for Lumiose City Prism Tower. Also, we don't know if there's a Pokemon stage for the WiiU version yet.
Speaking of Stages, a two new online option has been added: "For Fun" or "For Glory". In "For Fun", any stage (except for Final Destination) is chosen at random, items turned out, and only # of wins will be shown. In "For Glory", the only stage is Final Destination with no items and the players # of wins & loses are shown. Why do I mention this? Well since just battling on the normal Final Destination would get repetitive and boring, it's been said ALMOST all Stages have been given a Final Destination mode for for "For Glory".

How this stage works is that you begin at the base of Prism Tower, but soon the fighters are lifted up and fight on a platform as it floats around the tower. The picture above shows Prism Tower during daytime, but there are also scenes of the platform flying around the tower at night though this is most likely just a cosmetic change at time goes on. It's similar to past Stages like Delfino Plaza, Halberd, and Port Town Aero Dive. Because, it's likely it'll get a "Final Destination" mode where the whole battle takes place at the base of Prism Tower.
(4.) Items, New Modes, Stages? Blah, blah, blah, what you REALLY want to hear about are the Fighter Characters, specifically for Pokemon. Well I got news for you:
First, Lucario. Lucario's Aura attacks have been made more powerful than they were in Brawl, though now it looks like you can overpower Lucario which could result in it dashing across the Stage too far and fast, for example.
Also Lucario's Final Smash has been revealed and, as predicted, it has been changed from his Brawl's Aura Storm to now him Mega Evolving into Mega Lucario. Mega Lucario's Aura attacks will do max damage no matter how much damage he's at. It has not been confirmed if Mega Evolving is permanent, has a time limit (which is the most likely case), or has any other negative drawbacks.

Could it be possible that other Mega Pokemon may be Poke Ball Pokemon, or maybe even Master Ball Pokemon (its mentioned that rare Pokemon could also come out of the Master Ball, though it was never said what these "rare" Pokemon are)?
"NEW" VETERAN CHALLENGER:

That's right! Charizard returns but this time as his own fighter (doesn't look like Pokemon Trainer is returning, sadly)! Charizard comes with a whole batch of new Moves now that its free from Pokemon Trainer's control. However its biggest change is its (unconfirmed) Final Smash: Mega Carizard X!

But what of Mega Charizard Y? One theory going around is that, being this image of Mega Charizard X is from the WiiU version, that Mega Charizard Y could be for the 3DS version.
NEW CHALLENGER:

Didn't see this coming! Greninja is here to represent Gen VI and does so with ninja-like moves. It knows all the ninja tricks, probably giving Sheik a run for "his" money. Greninja's Final Smash was possibly also revealed where it just teleports around beating up an opponent (similar to how Latios & Latios worked in Brawl).

Let the Pokemon show you how its done!
Well, I'll finish this off with a link to the Nintendo Direct and to the Charizard & Greninja reveal trailer.
